求翻译：伴随抽油试采时间逐渐加长，抽油过程逐渐增多，油气田开发逐步转移到渗透能力差、油层深厚、储层能量不足的油藏。针对此类油藏，现在主要采用试采方式是有杆泵进行深抽。是什么意思？

Pumping test with gradually lengthening the time taken, the process of gradually increased pumping, oil and gas field development and gradually shifted to poor permeability, reservoir depth, reservoir energy is less than the reservoir. For these reservoirs, mining methods now used mainly test the de

The concomitance oil pumping tries to pick the time to lengthen gradually, the oil pumping process increases gradually, the oil-gas field development gradually shifts the oil deposit which to the seepage ability difference, the oil layer deep, reservoir undercapacity.In view of this kind of oil depo

With oil production test time gradually lengthened, pumping process is gradually increasing, oil and gas field development gradually shifted to poor penetration, deep reservoir and reservoir of low energy reservoir. For this type of reservoir, the main application of production test is Rod pump for
